PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 516,386, dated March13, 1894.

Application filed May 23,1893. Serial 110.475.287- (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY A. WISE WOOD, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented new and useful Improvement in Printing-Machines,of whichthe following is a specification. I

The aim of this invention is to produce a new and improved deliverymechanism for [0 cyl nder printing presses, and especially one whichshalldeliver the printed sheets printed side uppermost, always in fullsight, without contact of the printed surface with any part, and withoutthe use of grippers.

To this end, the invention consists of the devlce described and claimedin this specification, andillustrated in the accompanying drawings, inwhich Figure 1 is a side elevation of a printing press illustrating myinvention, Fig. 2 is a View similar to Fig. 1, the traveling carriagebelng in its opposite position. Fig. 3 is a plan of my improved deliverymechanism, and Figs. 4 to 7 inclusive are diagrammatic views 2 5illustrating the different positions of the delivery mechanism whilemanipulating a sheet.

My invention, broadly speaking, consists of two sets of intermeshingtapes, one set of which is bodily stationary, and the other set of whichis bodily moved so as to carry the sheet forward and deliver the sameupon the delivery table or delivery device; and the set of bodilymovable tapes is preferably what a lower speed than the speed of thestatlonary tapes, for a purpose hereinafter described.

Referring to the drawings, and in detail, A Arepresent the usual sideframes of the press, 1n which the parts are mounted in any of the 0usual manners.

B B represent the usual frames, which carry the shaft 0 of theimpression cylinder D, which frames B B are so operated that theimpression cylinder will be in contact with 4 5 the bed on the printingmovementof the same,

, guide-ways E, as shown, and moving on these guide-ways E is a suitablecarriage F, which carries the set of bodily movable tapes.

Arranged at the end of the press is the delivery table, or box G, whichis held by suitable supports g on the frames E, as shown, and at the endof this delivery table, I preferably arrange stops g, of any of theusual characters.

Arranged on the top of the traveling carriage F are a set of guides orshields H which are held in place by any suitable adjusting means, as hto shafts 48 secured between the frames of the carriage, as shown.

A set of the usual stripper-fingers I is arranged to operate inconnection with the impression cylinder D, as shown, and the impressioncylinder D is arranged to carry the usual set of gripper-fingers N,which manipulate the sheet on the cylinder.

Extending from the frames B are arms or hangers 10, in which hangers 10is journaled 7o the shaft 11, as shown. This-shaft 11 may, be positivelydriven from the impression cyliuder by means of a gear 14 secured to theback end of the impression cylinder, as shown in Fig. 3, by means of asuitableintermediate 13, and a gear 12 secured upon the shaft 11.Arranged on this shaft 11 are suitable tapepulleys 15, as shown, aroundwhich run tapes.

0n the frames Act the press, are also arranged hangers 17, in which isjournaled a a shaft 18, which carries tape-pulleys 1-9 opposite thetape-pulleys 15, and around which the tapes '16 pass. It will be seenthat this set of tapes 16 is thus bodily stationary, and that the sameis preferably so arranged that the tapes will travel at thesame speed asthe peripheral speed of the impression cylinder D; and by means of theusual stripper-fingers I, which may be actuated in any of the usualmanners, the sheet will run oif the im- 0 pression cylinder D onto thesetapes.

J ournaled in the frames of the carriage F is a shaft 20, which carriestape-pulleys 21, and running around which tape-pulleys 21 are the tapes22. These tapes 22 pass to tape pulleys 23 mounted on a shaft 24, whichis journaled in extensions 25 from the carriage frames F. It will beseen that the tapes 16 and 22 are intermeshed so that the tapes 22 canbe moved forward and backtoo ward without interfering with the tapes 16.Also it will be seen that the tapes 16 are set meshes.

on a slight incline, and that the tapes 22 are arranged in a horizontalposition, whereby, when the bodily movable tapes 22 are moved up closeto the impression cylinder, the head of the bodily movable tapes that isnearest to the impression cylinder will be below the tapes 16, as shownin Fig. 4.. These bodily movable tapes are preferably positively dr ven,but at a slower speed than the tapes 16, and one convenient way to drivethese tapes is by means of a gear 26 fastened on the front end of theshaft 11, which meshes with and drives a gear 27 mounted on a studsecured in the front bearing 10.

. Journaled in a suitable hanger 28 projectmg from the front bracket 10,and in a hanger 29 projecting from the front bracket 17 is a shaft 30.This shaft 30 is driven from the gear 27 by means of the bevel gears 31and 32, as shown. The shaft 30 is keyed or slotted, as at 34, as shown,and fitting on this shaft, so, as to nicely slide on the same, is thebevel gear 36, which has a collar 33, as shown, and fitting between thegear and the collar is a pro ecting yoke 35, extending out from thecarriage F, as shown. The bevel gear 36 meshes with and drives a bevelgear 37 secured on the shaft 20, as shown. By this means, it will beseen that as the carriage moves back and forth, the bevel gear 36 willbe slid back and forth on the shaft 30; but that by this means, theshaft 20 will be always positively turned at the same speed with theshaft 11, or slightly less, depending upon the reduction in the gearing,before described. The pulleys 21 and 23 are made smaller than thepulleys 15 and 19; and the whole is so arranged that the speed of thetapes 22 will be approximately about onehalf the speed of the tapes 16.A shaft 38 is mounted in bearings carried by the frames A, and carriestwo gears 39, which mesh into racks 40 secured to the under side of thecarriage frames, as shown. Also secured on this shaft 38, on the frontside thereof, is a pin- 1011 457 into which pinion 47, the segment 41This segment 41 is pivoted as at 42.

43 represents a shaft, which is mounted in the framing of the machine inany desired manner, and is preferably driven by any suitable gearing,not necessary here to describe, so as to turn once for each tworevolutions of the impression cylinder D, if my invention is applied tothe ordinary two revolution cylinder printing press. This shaft 43carries a disk 4st, which disk 44 has a crank-pin 45, which connects bypitmen 46 to a crank-pin 47, carried by the segment 41. By this means,

the carriage F will be reciprocated forward and backward.

The operation of my improved device can be followed from thediagrammatic figures.

In Fig. 4, the sheet S is shown as just being stripped off of theimpression cylinder, In

and as running out on to the tapes 16.

this position of the parts, the carriage F is arranged so as to beapproximately at ts right-hand position.

In Fig. 5, the impression cylinder is supposed to have made half arevolution, and the sheet S to be now entirely upon the tapes l6; and itwill be noted that the tapes 22 have been moved forward so that thefront end of the sheet will rest partially upon these tapes 22, asshown.

In Fig. 6, the impression cylinder is supposed to have made another halfrevolution, and to have taken a second sheet S down on the same, asshown, the first sheet S 1n the meantime having been carried forward onthe tapes 22, which tapes 22 are also moving in a direction to force thesheet forward. This will cause the sheet S to run off of the tapes 22around the tape pulleys 23 down on to the table G, as shown. Now, duringthe next half revolution of the impression cylinder, the carriage F willmove backward, and the tapes 22 will be gradually peeled away from underthe sheet S, and the sheet S will be allowed to drop on the deliverytable, as shown. I preferably drive the carriage F by a crank, as beforedescribed, and this crank gives a very nice and appropriate action tothe carriage, in that the same will start up gradually while the sheetfirst runs on to the tapes 22, and in that the same will start backgradually when the tapes commence to peel from under the sheet. Thiswill keep the sheet S firmly against the stop g, and will nicely andcorrectly deliver the sheet printed side uppermost on the table G. Ofcourse, any other suitable mechanism, as a cam could be used, ifdesired, to actuate the carriage F. The guard or shield II placed abovethe tapes 22, will prevent the sheet from being displaced, or fromcurling up during its forward motion.

By my improved device, the sheet will be delivered from the ordinaryprinting press, printed side up, without the use of grippers, andwithout the contact of the printing surface with any of the parts.

My invention, of course, is applicable to any form of cylinder printingpress, whether the same is a single or multi-revolution press, orwhether the same has one or more cylinders, or whether the cylinderoscillates.

The details of the invention herein shown and described, may be greatlyvaried by a skilled mechanic without departing from the scope of myinvention as expressed in the claims.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination in a delivery mechanism of two sets of tapes, on toone set of which the sheet first passes, the second set intermeshingwith the first set, and taking the sheet from the first set, anddelivering-the same, the
